Key Components:
- Weighing Platform: The area where the user stands for weight measurement.
- Column: Supports the height rod and poise bars.
- Height Rod: Extendable rod for measuring height.
- Poise Bars: Used to adjust and read weight measurements.
- Zero Adjustment Knob: Located near the poise bars, used to calibrate the scale to zero.
5. Setup and Assembly
Follow these steps to assemble and prepare your scale for first use:
- Unpack Components: Carefully remove all parts from the packaging. Inspect for any shipping damage.
- Assemble Column: Attach the column to the heavy-duty steel base/platform according to the instructions in the included Assembly Guide. Ensure all fasteners are securely tightened.
- Install Height Rod: Slide the height rod into its designated slot on the column. Ensure it moves smoothly and quietly.
- Initial Calibration (Zeroing): Before first use and periodically thereafter, ensure the scale is zeroed. With no weight on the platform, adjust the zero adjustment knob until the poise bars balance perfectly at the zero mark.
6. Operating Instructions
6.1 Taking a Weight Measurement
- Ensure the scale is on a firm, level surface and is properly zeroed.
- Instruct the individual to remove heavy clothing and shoes for the most accurate reading.
- Have the individual step onto the center of the weighing platform, standing still and looking straight ahead.
- Adjust the larger poise bar first to the nearest increment below the estimated weight, then fine-tune with the smaller poise bar until the beam balances.
- Read the weight indicated by the poise bars.
- Help the individual step off the scale carefully.
6.2 Using the Height Rod
The professional Silent Slide® height rod measures from 24 inches to 84 inches (by 1/8 inch increments) or 60 cm to 213 cm (by 1 mm increments).
- Ensure the individual is standing on the scale platform, facing forward.
- Extend the height rod upwards until the headpiece is above the individual's head.
- Gently lower the headpiece until it rests lightly on the top of the individual's head, ensuring their posture is straight.
- Read the height measurement indicated on the height rod.
- Retract the height rod for storage or for the next measurement.
7. Maintenance
Proper maintenance ensures the longevity and accuracy of your scale:
- Cleaning: Wipe the scale surfaces with a soft, damp cloth and a mild, non-abrasive cleaner. Do not use harsh chemicals or immerse the scale in water.
- Inspection: Periodically check all fasteners and connections to ensure they are secure.
- Storage: Store the scale in a dry, stable environment away from extreme temperatures and direct sunlight.
- Calibration Check: Regularly check the zero calibration of the scale. If consistent inaccuracies are observed, professional recalibration may be required.
8. Troubleshooting
If you encounter issues with your Health o Meter 402KL scale, refer to the following common problems and solutions:
- Inaccurate Weight Readings:
- Ensure the scale is on a perfectly level and stable surface.
- Verify the scale is properly zeroed before each use.
- Check for any obstructions under the platform or around the moving parts.
- Height Rod Not Sliding Smoothly:
- Clean the height rod and its track to remove any dust or debris.
- Ensure no components are bent or damaged.
- Scale Wobbles:
- Confirm the scale is placed on a flat, even floor.
- Check that all assembly bolts and screws are tightened securely.
